This book was released on 2017 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compelling astrophysical evidence for dark matter on one hand and the experimental evidence for neutrino masses on the other, demands modifications beyond the Standard Model. Therefore, building new models by extending the symmetries and particle content of the Standard Model is being pursued to remedy these problems. In this thesis, various models along with their predictions are presented. First, a gauge SU(2)N extension of the Standard Model, under which all of the Standard Model particles are singlet is introduced. The inverse seesaw mechanism is implemented for neutrino mass, with the new gauge boson as a dark matter candidate. The second paper is a gauge B-L extension of the Standard Model which breaks down to Z3, and it includes a long-lived dark matter candidate. The next model assumes that leptons do not couple directly to Higgs, and one loop mass generation is considered with important consequences, including Higgs decay, muon anomalous magnetic moment, etc. We then look at a U(1) gauge extension of the supersymmetric Standard Model, which has no [mu] term, and the Higgs boson's mass supersymmetric constraint is relaxed. The next model is a gauge B-L extension of the Standard Model with radiative seesaw neutrino mass and multipartite dark matter. We then consider another gauge U(1) extension under which quarks and leptons of each family may transform differently, while flavor-changing interactions are suitably suppressed. The next paper has an unbroken gauge SU(2) symmetry, which becomes confining at keV scale. We discuss the cosmological constraints and the implications for future e +e- colliders. Finally, an alternative left-right model is proposed with an automatic residual Z 2 × Z3 symmetry, such that dark matter has two components, i.e., one Dirac fermion and one complex scalar.

Kursunogammalu and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Conference, Orbis Scientiae 1996, focused on the topics: The Neutrino Mass, Light Cone Quantization, Monopole Condensation, Dark Matter, and Gravitational Waves which we have adopted as the title of these proceedings. Was there any exciting news at the conference? Maybe, it depends on who answers the question. There was an almost unanimous agreement on the overall success of the conference as was evidenced by the fact that in the after-dinner remarks by one of us (BNK) the suggestion of organizing the conference on a biannual basis was presented but not accepted: the participants wanted the continuation of the tradition to convene annually. We shall, of course, comply. The expected observation of gravitational waves will constitute the most exciting vindication of Einstein's general relativity. This subject is attracting the attention of the experimentalists and theorists alike. We hope that by the first decade of the third millennium or earlier, gravitational waves will be detected, opening the way for a search for gravitons somewhere in the universe, presumably through the observations in the CMBR. The theoretical basis of the graviton search will take us to quantum gravity and eventually to the modification of general relativity to include the Planck scale behavior of gravity -at energies 19 of the order of 10 Ge V.
Download or read book Dark Matter Neutrinos And Our Solar System written by Nirmala Prakash and published by World Scientific. This book was released on 2012-10-31 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark Matter, Neutrinos, and Our Solar System is a unique enterprise that should be viewed as an important contribution to our understanding of dark matter, neutrinos and the solar system. It describes these issues in terms of links, between cosmology, particle and nuclear physics, as well as between cosmology, atmospheric and terrestrial physics. It studies the constituents of dark matter (classified as hot warm and cold) first in terms of their individual structures (baryonic and non-baryonic, massive and non-massive, interacting and non-interacting) and second, in terms of facilities available to detect these structures (large and small). Neutrinos (an important component of dark matter) are treated as a separate entity. A detailed study of these elusive (sub-atomic) particles is done, from the year 1913 when they were found as byproducts of beta decay — until the discovery in 2007 which confirmed that neutrino flavors were not more than three (as speculated by some).The last chapter of the book details the real-time stories about the “regions” that were not explored thus far, for lack of advanced technology. Their untold fascinating stories (which span up to 2010) are illustrated here datewise in full.The book concludes with the latest news that the Large Hadron Collider team at CERN has finally succeeded in producing 7 trillion electronic Volts of energy by creating head-on-collisions of protons and more protons (in search of God-particle). The energy produced was three times more than previous records.
Download or read book The Standard Model and Beyond written by Paul Langacker and published by CRC Press. This book was released on 2009-12-01 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model and Beyond presents an advanced introduction to the physics and formalism of the standard model and other non-abelian gauge theories. It provides a solid background for understanding supersymmetry, string theory, extra dimensions, dynamical symmetry breaking, and cosmology. The book first reviews calculational techniques in field theory and the status of quantum electrodynamics. It then focuses on global and local symmetries and the construction of non-abelian gauge theories, before explaining the structure and tests of quantum chromodynamics. The book also describes the electroweak interactions and theory, including neutrino masses. The final chapter discusses the motivations for extending the standard model and examines supersymmetry, extended gauge groups, and grand unification. Thoroughly covering gauge field theories, symmetries, and topics beyond the standard model, this text equips readers with the tools to understand the structure and phenomenological consequences of the standard model, to construct extensions, and to perform calculations at tree level. It establishes the necessary background for readers to carry out more advanced research in particle physics. Supplementary materials are provided on the author’s website and a solutions manual is available for qualifying instructors.
Download or read book Particles Strings and Cosmology written by Kiwoon Choi and published by Springer Science & Business Media. This book was released on 2005-12-12 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: PASCOS is an interdisciplinary symposium on the interface of of Particle physics, String theory and Cosmology. Over the past two decades these three disciplines have increasingly become closer. Historically there was always a strong overlap between particle physics and cosmology. This connection has become even stronger with the realization that some of the fundamental issues in cosmology such as the presence of dark matter and dark energy may possibly find a resolution only via new theories of particle physics. At the same time string theory has begun to play an increasingly important role in particle physics as a possible framework for building unified models of particle interaction including gravity. In recent years we have seen an increasing overlap between cosmology and string theory and currently the area of string cosmology is one of the most active fields of research. PASCOS 2005 aimed to provide coherent discussions of recent developments on the interface of the three disciplines and also on their interconnections. In particular, superstring aspects in low energy particle theory (SUSY) and cosmological applications (moduli stabilization) are extensively covered in this volume. Topics include dark matter and dark energy, baryogenesis, flavor and CP violation, neutrino physics, supersymmetry and extra dimensions, flux compactification, string model building, as well as brane cosmology.

Download or read book Beyond the Standard Model written by Ofri Telem and published by . This book was released on 2019 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model (SM) of particles and interactions provides some of the most extensively tested predictions in science. However, it does not adequately describe quantum gravity, and does not contain a suitable candidate for Dark Matter. Furthermore, the UV sensitivity of the SM Higgs sector suggests that new states beyond the SM might exist at energies not far above the weak scale. This dissertation explores potential scenarios for physics beyond the SM, either in a dark sector or linked to the Higgs sector of the SM. The first part of this work includes two novel classes of composite Higgs models, with far reaching phenomenological consequences. In the first of these, an adjustable tree-level Higgs quartic coupling, allows for a significant reduc- tion in the tuning of the Higgs potential. The quartic in this model originates from the dimensional reduction of a 6D theory, and is the first example of a holo- graphic composite Higgs model with a tree-level quartic. In the second novel class of composite Higgs models, the top and gauge partners responsible for cut- ting off the Higgs quadratic divergences form a continuum. A concrete example is presented, based on a warped extra dimension with a linear dilaton, where this finite gap appears naturally. Spectral densities are derived for this model, as well as the full Higgs potential for a phenomenologically viable benchmark point, with percent level tuning. The continuum top and gauge partners in this model evade all resonance searches at the LHC and yield qualitatively differentcollider signals. The second part of this work features two different classes of models for an extended dark sector that undergoes either confinement or bound states forma- tion. It is shown how each of these mechanisms could lead to vast modifications of early universe dynamics, as well as unique signals today. In the first of these, the relic abundance of heavy stable particles charged under a confining gauge group is depleted by a second stage of annihilations near the deconfinement temperature. This mechanism can be used to construct ultra-heavy dark-matter models with masses above the naive unitarity bound. The second contribution is Self-Destructing Dark Matter (SDDM), a new class of dark matter models which are detectable in large neutrino detectors. In this class of models, a com- ponent of dark matter can transition from a long-lived state to a short-lived one by scattering off of a nucleus or an electron in the Earth. The short-lived state then decays to SM particles, generating a dark matter signal with a visible en- ergy of order the dark matter mass rather than just its recoil.

Download or read book Gauge Extensions of the Standard Model written by Corey M. Kownacki and published by . This book was released on 2018 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though it appears to describe the world well to at least the electroweak scale, the Standard Model is becoming increasingly inadequate: it can fit fermionic masses but offers no explanation for the observed hierarchy; it provides no mechanism for generating neutrinos mass; and lastly, but perhaps most significantly, it is absent any dark matter candidate. Myriad extentions exist that are able to accommodate these problems individually including the many models that resort to ad hoc symmetries to protect dark matter. Here, extensions are motivated by generalizations of symmetries contained in the Standard Model (such as B-L) or symmetries introduced to enhance Standard Model structure. In the first part we study generalizations of U(1) gauge extensions such a B-L and I3R. For generalized B-L, we allow families to transform differently from one another and study the resulting flavor-changing neutral current constraints. In the next project, to incorporate dark matter to the puzzle, we then implement the scotogenic mechanism to generate neutrino mass via the Type II seesaw with interesting collider signatures coming from the double charged scalar. The next extension is a U(1) family symmetry that is also a dark symmetry, in both cases coupling exclusively to right-handed objects. We then push to explore Alternative Left-Right models both individually and as low-energy subgroups of the unified trinification and quartification models. We uncover naturally emerging dark symmetries for certain breaking patterns and investigate phenomenological signatures that arise from dark matter and glueball-like states of leptonic color. Obtaining gauge coupling unification at one-loop imposes further constraints on the possible symmetry breaking patterns as well as permissible low-energy particle content.

Available in PDF, EPUB and Kindle. Book excerpt: Supersymmetry is at an exciting stage of development. It extends the Standard Model of particle physics into a more powerful theory that both explains more and allows more questions to be addressed. Most importantly, it opens a window for studying and testing fundamental theories at the Planck scale. Experimentally we are finally entering the intensity and energy and sensitivity regions where superpartners and supersymmetric dark matter candidates are likely to be detected, and then studied. There has been progress in understanding the remarkable physics implications of supersymmetry, including the derivation of the Higgs mechanism, the unification of the Standard Model forces, cosmological connections such as a candidate for the cold dark matter of the universe and consequences for understanding the cosmological history of the universe, and more.This volume begins with an excellent pedagogical introduction to the physics and methods and formalism of supersymmetry which is accessible to anyone with a basic knowledge of the Standard Model of particle physics. Next is an overview of open questions, followed by chapters on topics such as how to detect superpartners and tools for studying them, the current limits on superpartner masses as we enter the LHC era, the lightest superpartner as a dark matter candidate in thermal and non-thermal cosmological histories, and associated Z' physics. Most chapters have been extended and updated from the earlier edition and some are new.This superb book will allow interested physicists to understand the coming experimental and theoretical progress in supersymmetry and the implications of discoveries of superpartners, and will also help students and workers to quickly learn new aspects of supersymmetry they want to pursue.
